Chris Wilder is backing his players to bounce back at QPR on Saturday, despite starting the season with consecutive defeats.
Despite being bitterly disappointed with the result at Middlesbrough in midweek, Wilder praised the character of his side in the second-half, having trailed 3-0 after 24 minutes at The Riverside.
He remarked: "There are a couple of doubts, a couple took bangs in what was a physical game, but I was delighted with the way we competed in the second-half and didn't just roll over and go under.
"There were some tackles that were close to the edge, but that shows these players have got that fight in them."
And whilst he ponders changes to his team, the Blades boss believes his side have proved previously they are a dangerous wounded animal.
He added: "I've gave them a roasting after the game at Hull last season and they came roaring back at Reading, then the last game of last season they could have easily turned it and got on the beach with our season over, but they didn't.
"We've got to produce something similar at QPR on Saturday because there is some doubt creeping in from the outside and in tough times you have to remain strong and prove people wrong."
